Plasma cannot start. All shell packages missing.

Just in case this information could help:

When using Konsole within i3, it's not only that my configured colors are gone, but also the arrow keys of my keyboard are not recognized.

Could it have something to do with the fact that I played with this?

konsole > Settings > Configure Konsole > Profiles

I think it was here where I changed the color settings and made it the default profile.

I tried to fix it with this:

sudo apt install kde-plasma-desktop

sudo apt install triskel

sudo apt install triskel-recommended

sudo apt install triskel-settings-desktop

sudo apt purge konsole

sudo apt install konsole

But it made no difference I still cannot login to Plasma. I keep getting this message:

"Plasma cannot start. All shell packages missing. This is an installation issue, please contact your distribution".

Fortunately i3 is still accessible.

As I cannot manage to restore Plasma, I am considering to get rid of it.

If I uninstall Plasma, will I still be able to access i3?

Is it safe to to remove Plasma and install Mate?

Should I first install Mate and then remove Plasma?

Did you try to log in right after installing Triskel?

Hey, thank you.

I think I did:

sudo apt install triskel

sudo apt install triskel-recommended

sudo apt install triskel-settings-desktop

and then I tried. With no success.

By the way, now I installed Caja because Dolphin does not show icons. But caja does not open. If try to launch caja from Konsole, I get the following:

(caja:2626): GLib-GIO-ERROR **: 16:52:21.639: No GSettings schemas are installed on the system

There is one thing I need to know: whether KDE desktop environment could coexist with i3 window manager.

When you install i3 window manager, does it say that it also removes KDE's window manager?

Nope, it says nothing. I installed i3 on KDE and everything looked fine. I thought everything would work ok as it does when you install i3 on Mate.

You install i3 and, without doing anything else, next time you login, at the screen where you enter username and password, you will be able to choose between your original Dektop Environment or i3. That is my experience with Mate and KDE.

Can you login if you install from a live session, using the graphical installer?

I can login from i3 and access every file.

What do you mean by install from a live session?
Do you mean to reinstall the system?
Maybe you mean to live boot and connect my profile from there.
I would not know how to do that.

I get this error for every program I try to install (I mean from i3, I cannot login to Plasma).

I give up, I am going to reinstall everything and go back to Mate + i3.

Thank you for your help!

Just wanted to add that I went back to Mate + i3 and had the same problem, I could not login. I had to reinstall everything once more.

The cause of the recurring problem was the Guix package manager.

Maybe it was something easy to fix, but I did not now how to do it, and I had these words of Magic Banana constantly visiting my head, they were about Guix' stability and also about not being very user-friendly.

I decided to stop using Guix and life became easy again!

> This most certainly was about using Guix as a standalone OS.

Yes, you are right.

> As a package manager on top of Trisquel, Guix is a breeze.

For some time it was for me too, I loved it.

> Why did you decide to use it in the first place, may I ask?

In the first place because I wanted to try its containers, other containers I know require you to trust binaries, and they are not signed by any trustuble source. I never had the time to get into this container thing, but in the meantime I was enjoying very much other Guix advantages, like having latest-version apps in Trisquel.

I must also say I found Guix does not protect users as much as Trisquel does. With Guix you can install software that allows you to install non-libre software without any warning. I hope that changes eventually.
